I felt a bit confused with the trap part of the song. It started off like some sort of trance. After the drop that instrument was very off key. And the majority of the song was just a sped up version of the original. I suggest sampling the original song and maybe changing the beat pattern.
i did not understand what u say.
150 BPM is the most common tempo for scouse/donk.
The melody starting at the 1 minute mark was again because everyone does that ;d.
